The crash marked the third EagleMed helicopter accident in the past three years and sparked an evaluation of the Kansas-based company's accreditation.

Less than four months ago, an EagleMed helicopter crash-landed outside an Oklahoma City nursing home, killing two people onboard and critically injuring a third. Another EagleMed helicopter crashed into a field near Kingfisher, Okla., on July 22, 2010, killing the pilot and nurse and seriously injuring a paramedic.

The Commission on Accreditation of Medical Transport Systems will now examine the company's safety practices and determine if EagleMed is at fault for the crash.

"Currently, EagleMed is working with the NTSB and FAA," EagleMed spokesperson Robbie Copeland said in a statement. "We're helping them with their investigation by providing the information they need from us."
